Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional prediction methods are used for energy consumption, then device complexity is reduced, but measurement precision of energy demand and production balance deteriorates
Solution Approach 1:
The patent introduces an electrical power management entity as an intermediary between power consuming devices and the power grid. This entity collects consumption profile information, receives control information, and coordinates power usage to achieve precise balancing of energy demand and production without requiring complex modifications to individual devices.
Solution Approach 2:
The system implements feedback mechanisms where consumption profile information is continuously collected from power consuming devices, compared against production capabilities, and control information is sent back to adjust consumption patterns. This closed-loop feedback enables precise measurement and adjustment of energy demand to match production.
2Reliability
If costly balance energy sources are deployed to stabilize the network, then network stability is improved, but energy cost increases
Solution Approach 1:
The system performs preliminary actions by collecting and analyzing consumption profile information in advance, enabling the electrical power management entity to predict future energy demand patterns. This allows proactive scheduling of power consumption to match renewable energy production availability, preventing the need for costly balance energy sources to stabilize the network later.
Solution Approach 2:
Power consuming devices are equipped with the capability to self-adjust their operation based on control information received from the electrical power management entity. Devices can autonomously modify their consumption patterns, activate different operational modes, or schedule operations to coincide with periods of high renewable energy production, thereby maintaining network stability without external stabilization resources.
3Object-generated harmful factors
If renewable energy sources are used for power generation, then environmental impact is reduced, but energy production variability increases
Solution Approach 1:
The system embraces the dynamic nature of renewable energy production by implementing flexible consumption scheduling. The electrical power management entity continuously adjusts power consumption patterns based on real-time and predicted production levels from renewable sources, allowing the system to adapt dynamically to varying wind, solar, or other renewable energy availability rather than requiring stable, predictable production.
Solution Approach 2:
The patent utilizes parameter changes in consumption patterns to match renewable energy production variability. By modifying operational parameters such as timing, duration, and intensity of power-consuming operations based on control information, the system aligns demand with the variable supply characteristics of renewable energy sources, maintaining stability despite production fluctuations.
